While no official reason was given, it's understood said originals - "Jesus, Mary and Joseph!" and "Minstrel Krampus" - feature sensitive content in light of today's tragic shooting at Sandy Hook Elementary School in Newtown, Connecticut.

The episodes will be replaced by repeats of "Grumpy Old Man" and "Wheels & The Legman and The Case of Grandpa's Key," respectively.

The network has likewise dropped the 7:00/6:00c repeat of "The Cleveland Show" ("Die Semi-Hard") in favor of a different encore installment ("Menace II Secret Society").

The previously announced originals for "The Cleveland Show," "The Simpsons" and "Bob's Burgers" however are still scheduled to air.

This is the second time in recent memory FOX has pulled "Family Guy" and "American Dad" originals: in April 2011, a hurricane-themed crossover (including "The Cleveland Show") was nixed after dozens of tornadoes devastated the South that same month. The episodes ultimately aired in October last year.
